Description

Technical Field

[0001] The utility model relates to the technical field of video monitoring, in particular to a video monitoring human-computer dialogue system based on a touch screen. Background Art

[0002] Traditional analog video surveillance systems mainly switch images and control the pan / tilt position by controlling the keyboard or computer mouse. However, such operation may be too complicated or inapplicable in some small systems or special systems. Therefore, it is necessary to develop a more concise and intuitive control method. Those skilled in the art provide a video surveillance human-computer dialogue system based on a touch screen to solve the problems raised in the above background technology. Utility Model Content

[0003] To solve the above technical problems, the utility model provides a video surveillance human-computer dialogue system based on a touch screen, including a touch screen display, a virtual keyboard graphic overlay and a USB signal processor. The virtual keyboard graphic overlay is used to overlay and display a virtual keyboard graphic on the touch screen display, and the USB signal processor is used to parse the touch information of the touch screen.

[0004] Preferably: the virtual keyboard graphic overlay and the USB signal processor are both connected to the video surveillance host.

[0005] Preferably: the user can switch images and control the pan / tilt position by touching the virtual keyboard graphic on the screen.

[0006] Technical effects and advantages of the utility model:

[0007] The utility model realizes the simple and intuitive operation of image switching and pan / tilt position control of the video monitoring system by using a touch screen display and specific hardware and software components, thereby improving the usability and efficiency of the system. At the same time, due to the use of a touch screen display, the system occupies less space and is more suitable for use in some small systems and special systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 is a structural schematic diagram provided by the present application, showing the connection method of the virtual keyboard graphic overlay and the USB signal processor on the video surveillance host; DETAILED DESCRIPTION

[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0010] See also Figure 1 The utility model provides a video monitoring human-computer dialogue system based on a touch screen. The system combines a touch screen display with a video monitoring host, and realizes the functions of image switching and pan / tilt position control through specific software and hardware components, thereby replacing the traditional control keyboard and display.

[0011] Specifically, the system adds two components to the video surveillance host:

[0012] 1. Virtual keyboard graphic overlay: This component is used to overlay and display the virtual keyboard graphic on the touch screen display. The user can directly see the virtual keyboard graphic on the touch screen and operate it by touching to switch the image and control the PTZ position.

[0013] 2. USB signal processor: This component is used to analyze the touch information of the touch screen. When the user operates on the touch screen, the USB signal processor will analyze the touch information and convert it into corresponding control instructions, and then perform the corresponding operations through the video surveillance host.

[0014] Through the coordinated use of the above two components, the utility model realizes the function of replacing the traditional control keyboard and display with a touch screen display, making the operation of the video monitoring system more concise and intuitive, and is very suitable for the requirements of some small systems and special systems.

[0015] The working principle of the utility model is:

[0016] When implementing the utility model, the virtual keyboard graphic overlay and the USB signal processor can be installed on the video monitoring host first, and then the two components can work normally through the corresponding software configuration. When using, the user only needs to touch the virtual keyboard graphic on the screen to switch the image and control the pan / tilt position.

[0017] The utility model realizes the simple and intuitive operation of image switching and pan / tilt position control of the video monitoring system by using a touch screen display and specific hardware and software components, thereby improving the usability and efficiency of the system. At the same time, due to the use of a touch screen display, the system occupies less space and is more suitable for use in some small systems and special systems.

[0018] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
